The Bluetooth SIG is releasing new specifications for version 4.0 of the popular wireless technology, allowing new low-energy health-monitoring devices to hit the shelves for the December holiday season.
The Bluetooth SIG
(Special Interest Group) is gradually rolling out specifications for a new
generation of health-monitoring wireless devices based on the low-energy
capabilities of Bluetooth 4.0.
Wireless device manufacturers are already designing prototypes of Bluetooth 4.0 health-monitoring devices, and mobile phone
manufacturers will embed the updated wireless specification in new products
beginning in the fourth quarter of 2011, in time for the holidays.
"It's a whole new architecture," Suke Jawanda, chief marketing officer for the Bluetooth SIG, told eWEEK. Many types of
devices could not connect previously using Bluetooth because they required too
much power, he noted. "A big battery pack is not going to happen with a
glucose meter," Jawanda said.
Founded in 1998, the Bluetooth SIG is a nonprofit trade association
governing the standards for Bluetooth wireless technology. All
incorporating Bluetooth technology into their devices join the
Bluetooth SIG, which now has 14,000 member companies.
On June 7, the Bluetooth SIG announced profiles for thermometer and
heart rate monitors. Bluetooth profiles are the set of rules ratified
the Bluetooth SIG and ready to be optimized for particular tasks, such
as monitoring heart rates or taking
blood glucose numbers
, Jawanda said.
"We have dozens and dozens of profiles that are optimized that allow certain devices to act accordingly," Jawanda said.
For the thermometer profile, companies will design a thermometer
path to transmit temperature readings to a patient's mobile phone
every half hour to allow a caregiver to keep track of the patient's
"All of that information can be sent to an application, and in one spot they've got a panorama of their health," Jawanda said.
On July 26, the Bluetooth SIG will publish on its Website several
other profiles, including Blood Pressure Profile and Search, which
allows patients to measure their blood pressure, then send the readings
mobile phone or PC using Bluetooth. Caregivers or doctors access the
information in the cloud and import the data into EHRs (electronic
records). Health insurance companies can also access the data through
"You can liberate data and turn it into information on a phone, on a PC and in the cloud," Jawanda said.
The number of Bluetooth-enabled medical devices on the market could
increase from 40 million to hundreds of millions over the next few
years, Jawanda said.
Heart rate, temperature and blood pressure monitors will be among
the first Bluetooth 4.0 devices available, followed by weight scales,
pedometers and new blood glucose meters.
Companies that make Bluetooth health-monitoring devices include
A&D Medical, Nonin, 3M and Omron. The devices are sold in retail
stores such as pharmacies and through health care providers.
By the end of 2012, 100 percent of smartphones will feature version
4.0, according to the Bluetooth SIG. Bluetooth 4.0 radios happen to be
cheaper and smaller than their 3.0 predecessors, Jawanda noted. "It's
just the way the silicon has been spun," he said.
To enable data to be transferred securely in the cloud, the Bluetooth SIG is working with the Continua
a nonprofit group of 230 companies in health care and technology that
certifies the devices as interoperable with other tech products.
Mobile health will be the first industry to benefit
from Bluetooth 4.0, followed by smart homes and fitness,
the Bluetooth SIG.
With 72 percent of physicians in the United States using smartphones, mobile
technology is a key driver of health care IT growth
, according to a report
by research firm RNCOS.
